Project mention: Why is Meta destroying its engineering organization? | news.ycombinator.com | 2026-06-16
Your comparison is like comparing The Eagles to some little local rock band!
Rather than two competitive products I think these are both market dominant products that reveal the engineering culture, values and impact of the two organizations.
I can say that when I first started with React I thought it sucked and looked at Vue and Svelte and similar things. My take on all of them was that they made the internal frameworks I was using to build very complex RIAs in the 2005-2010 time frame look like something that fell off a UFO.
I first thought Vue reflected the way I thought about conventional "webby" applications particularly in terms of treating lists as a first-class object. I eventually learned with React how to draw absolutely anything, even whole 3-d worlds!

I guess what I'll say about Svelte is "if you make such a radical change in your framework did you really believe in it?" Early on I stuck to controlled forms in React because uncontrolled forms seemed structurally unstable (add one too many features and it all breaks) and then I discovered

which is easy and very high performing.
